FortiGate-7040E chassis
Each PSU is designed to be installed in a Telecom data center or similar location that has available -48VDC power fed
from a listed 40A circuit breaker. To improve redundancy you can connect each power supply to a separate power
circuit.
DC power cables are intended to be used only for in-rack wiring, must be routed away from sharp edges, and must be
adequately fixed to prevent excessive strain on the wires and terminals.
DC terminals accept UL approved ring terminals for 8/M4 stud with ext ring diameter < 9.8 mm. DC cables must be a
minimum of 8 AWG.
The following table lists some key power data for each PSU.
